UNITEDSTATES PATIENT O F CE- JAMES JO LY, or BOLTON, ENGLANQJ OPENER FOR COTTON AND OTHER Application filed meat a, 1924, Serial No. 748.657. andiin Great Britain October 2, 1924.

This invention relates to apparatus forv opening or separating rawfibrous material such as cotton, wool or the like known as hopper bale breakers or openers,.or other machines for similar purposes. 7

These machines usually embody a hopper to receive the raw fibers, an inclined travelling spiked lattice to pick up the fibers from the hopper, a rotary evener roll to remove 10 and throw back into the hopper unopened tufts of fibers from the spikes of the lattice,

and a rotary clearer roll to clear the fibers from the spikes and throw them forward.

According to this invention I provide the machine with additional sets of spiked apparatus between the spikes of which the fibers i e ofthe lattice .E and delivers them down a will be passed and which will further separate and open the fibers before delivery from the machine.

, The invention will be fully described with reference to the accompanying drawings.

Fig. 1 is a sectional side elevation of one embodiment of the invention.

Fig. 2 is a sectional side elevation of another embodiment of the invention.

Fig. ,3. is a detail view of the adjusting frame for one of the additional spiked lattices.

Fig. 4 is a transverse section of Fig. '3.

The apparatuscomprises a hopper or receptacle A, a spiked feed lattice B, a rotary spiked roller 0 to even or regulate the amount of fiber carried forward on the spikes a of the lattice, and a clearer roller D to remove or deliver forward the fiber from the spikes a, all of which are of ordinary or known construction and disposition.

According to the invention at the delivery side of the spiked lattice A and clearer rollers C and D a second travelling'spiked lattice E is mounted which. operates in conjunction with moving or fixed spikes F in close proximity to the spikes E. The fibers are passed between the spikes F and E which 4' operate upon the fibers to open any'large tufts that have been fed forward by the feed lattice.

In the form of the invention shown in Fig. 1, the additional spiked apparatus comprises a travelling spiked lattice E and a travelling spiked lattice F, both preferably travelling in the same direction to deliver the fiber, the" lattice F travelling at a slower speed, though it may be stationary or may even travel in the reverse direction to the lattice E.

The spikese of the lattice E are set to car disentangle: any lumps of fiber, carried for-.

ward by the lattice E. The lattices E and F are preferably set horizontal, though if found convenient may be inclined, and the rollers G over which the lattice F travels may be mounted in adjustable bearings 9 so that the distance between the two lattices may be altered as required for different grades or types of fiber. The lattice E may be mounted in a frame H at each side of the apparatus, as shown in Fig. 3. A clearer roller 1C takes the fibers from the spikes chute L or on to a travelling band.

In the form of the invention shown in Flg. 2 the additional spikedapparatuscmn I prises an extension M of the original inclined spiked lattice B around an extra roller or carrier m presenting a horizon'tal'or inclined surface E after passing the first evener roll C and a' second adjustable spiked travelling lattice F applied thereto and preferably travelling more slowly in the same direction. An adjustable slide N may be placed underthe extended part of the lattice to keep it from sagging and the bottom bearing 112 may be adjustable to keep the lattice taut. A clearer roller K takes the fibers from'the spikes m of the lattice M and delivers them down a chute L or on to a travelling band.

What I claim as my invention and desire to protect by'Letters Patent is 1. In a machine for opening cotton or ported, and a third lattice associated with and movable in proximity tothesupported stretch of said second lattice and having- .spikes .set in a direction opposite to the spikes of the'second lattice to straighten out 105 lumps of fiber, means for moving said third lattice toward and away from the supported stretch of said second lattice to vary the distance between'said second and third lat- 0nd lattice moves and by which it is sup- .tices, and a clearer roller to remove. the

fibers from the spike of said second and third lattices and deliver said fibers in a forward direction.

2. A machine for opening cotton and other fibers comprising a hopper, to receive the fibers, an upwardly projecting, traveling, spiked lattice to lift the fibers fromthe hopper, an. even-er roll associated with said lattice to prevent large lumps of fiber being carried forwardly, a clearer roll to remove the fibers froin a portion of the spiked lattice, an auxiliary spiked lattice to which the fibers are delivered and; having" another lattice in closec'ooperating proximity thereto, and movable towards and from the same tovary the distance between the spikes of the two latter lattices, thespikes-Jof the lattices beingsetin opposite directions tostraighten outlumps of fiber, the lattice operating in proximity to'theauxiliary spiked lattice being movable relatively to the said auxiliary lattice and; at: a. slower speed than the latter to straighten out and even the fibers, and a clearer roller to remove the fiber's from the spikes of the auxiliary lattice and the lattice in proximity thereto and deliver the fibers in a for'wardd irection.

In testimony whereof I have'hereunto set my hand. I

JAMES JOLLY.
